RACD holds 2t + 3 tracks.
Write and simplify an expression for the
number of tracks on 4 CDs.
When t = 15, how many tracks are there on
4 CDs?
The number of tracks on 4 CDs are 132.
Here, we are given that a CD holds 2t + 3 tracks.
Thus, the number tracks on 4 CDs will be given as-
4(2t + 3)
Simplifying the expression further, we get
(4 × 2 × t) + (3 x 4)
= 8t + 12
Therefore, the expression for the number of tracks on 4 CDs is 8t + 12
Now, if t = 15
Then, the number of tracks on 4 CDs can be found by substituting the value t = 15 in the expression (8t + 12)
= 8(15) + 12
= 120 + 12
= 132
Thus, there are 132 number of tracks on 4 CDs.

One angle in a triangle has a measure that is three times as large as the smallest angle. The measure of the third angle is 40 degrees more than that of the smallest angle. Find the measure of the LARGEST angle.
Answer: The LARGEST angle has a measure of
degrees.
The measure of the largest angle is 84°
How to compute the value?It should be noted that the total angles on a triangle is 180°.
Let the smallest angle = x
Second angle = x + 40
Third angle = 3x
Therefore 3x + x + x + 40 = 180
5x = 180 - 40
5x = 140
x = 140/5
x = 28
Therefore, the largest angle will be:
= 3x
= 3 × 28°
= 84°
Therefore, the measure of the largest angle is 84°

Rewrite y =
1/4x+3,
solving for x. What feature of the line can easily be found using the rearranged equation?
The solution of the equation for x is x = 4y - 12
What are inverse functions?Inverse functions are the opposite of an original equation. This means that for a function f(x), the inverse of the function f(x) is f-(x); it also represents the opposite function
How to rewrite the equation of the function?The function y is given as
y = 1/4x + 3
As a general rule, we start by writing y as a variable (say y = f(x)).
So, the equation of the function becomes
y = 1/4x + 3
The next step is to switch/swap the positions of x and y in the above equation y = 1/4x + 3 (in this case, it is not necessary)
So, the equation remains the same
y = 1/4x + 3
The next step is to make x the subject of the formula in the above equation y = 1/4x + 3
The equation becomes
1/4x = y - 3
This is done by subtracting 3 from both sides of the equation.
So, we have:
1/4x = y - 3
Multiply through the sides of the equation by 4
So, we have
x = 4y - 12
Express as an inverse function
f-1(x) = 4x - 12 --- this is not compulsory
So, the solution of the equation for x is x = 4y - 12
Hence, the rewuired solution of the equation for x is x = 4y - 12

PLEASE HELP ME!!!!!!How is the product of a complex number and a real number represented on the complex plane?
Consider the product of −2+8i and 5.
Drag a value or phrase into each box to correctly complete the statements.
The complete paragraph is shown:
The complex number - 2 + i 8 has modulus of 2√17. When - 2 + i 8 is multiplied by 5, the modulus of the product of 10√17.
Multiplying a complex number by a real number is a scalar of a complex number. The quadrant location of the complex number and its product with the real number are the same.
How to make operations with complex numbers
In this problem we have a paragraph, in which we must fill the blanks with the results of operations with complex numbers. The modulus of a complex number is found by using the Pythagorean theorem:
r = √[(- 2)² + 8²]
r = √(4 + 64)
r = √68
r = 2√17
And the product between the real number and the complex number is done by distributive property:
5 · (- 2 + i 8)
5 · (- 2) + i (5 · 8)
- 10 + i 40, whose modulus is 10√17.
Graphically speaking, the scalar of a complex number remains in the same quadrant of the complex plane.

Assume that women’s heights have a distribution that is symmetric and unimodal , with a mean of 69 inches and the standard deviation is 1.5 inches
Using the normal distribution, the height of a woman with a z-score of -1.5 is of 66.75 inches.
What is the missing information?The problems asks for the height of a woman with a z-score of -1.5.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.For this problem, the parameters are given as follows:
[tex]\mu = 69, \sigma = 1.5, z = -1.5[/tex]
The height is found solving for x, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
-1.5 = (X - 69)/1.5
X - 69 = -1.5 x 1.5
X = 66.75.
The height of a woman with a z-score of -1.5 is of 66.75 inches.
